Allopurinol can cause gastrointestinal upset. Common issues include nausea, diarrhea, and abdominal pain. These usually are mild and resolve on their own. However, more serious issues are possible.
Managing Mild Gastrointestinal Side Effects
Try taking Allopurinol with food or milk to lessen stomach irritation. If nausea persists, your doctor might suggest taking the medication at bedtime. Staying hydrated is also key to managing diarrhea.
Understanding Serious Gastrointestinal Complications
Rarely, Allopurinol can cause pancreatitis (inflammation of the pancreas) or gastrointestinal bleeding. These are serious conditions requiring immediate medical attention. Symptoms of pancreatitis include severe abdominal pain, nausea, vomiting, and fever. Signs of gastrointestinal bleeding include dark, tarry stools or vomiting blood.
When to Consult a Doctor
Seek immediate medical care if you experience any of the following: severe abdominal pain, persistent vomiting, bloody stools, or signs of dehydration (such as decreased urination or dizziness).
